PACKING-BOX FOR TIN-PLATE.

SPECIFICATION formingpart of Letters Patent No.'654,9 13, dated July 31,1900. Application filed December 61 1899. Serial No. 739,372- (NOmodel.)

To aZZ whom it may concern.-

Be it known that I, JOHN G. MCILWRAITH, a citizen of the United States,residing at Anderson, in the county of Madison and State of Indiana,have invented certain new and useful Improvements in Packing-Boxes forTin- Plate, of which the following is a specification.

The object of my present invention is to provide a cheap, light,symmetrical, and per fectly-dry box for tin-plate. Such boxes haveheretofore been made wholly of wood. Suitable material for the purposeis becoming scarce and expensive and when of suitable thickness adds tothe bulk and weight of the packages considerably. Such boxes must beperfectly dry, and consequently tin plate manufacturers, as well as boxmanufacturers. are obliged to carry a very large stock on hand in orderto insure a supply at all times of the proper quality, and this initself requires large buildings for store-rooms. I have found itpossible to produce a waterproofed pulp-board which while comparativelyvery thin is sufficiently strong for the purpose and is of much lessbulk and weight than any Wood suitable for the purpose, and I havesucceeded by means of my invention in producing a box the sides of whichare composed of this materialand which is both better and less expensivethan boxes composed wholly of Wood. While as this material when manufactured is always perfectly dry, such boxes possess the additionaladvantage of requiring less storage-room to keep an ample supply onhand.

Referring to the accompanying drawings, which are made a part hereof,and on which similar characters of reference indicate similar parts,Figure l is a perspective view of a box embodying my present invention,and Fig. 2 is a transverse vertical sectional view of the same as seenfrom the dotted line 2 2 in Fig. 1.

The sides and ends of the box are composed of wooden strips 1 and arenailed together at the corners. The tops and bottoms 2 are composed ofpulp-board, as above described, of a very tough and strong quality, butcomparatively thin, and are nailed to the strips 1. Reinforcing-strips 3are provided, as

shown, extending along the greater portion of the length of each edge ofthe box, and these serve to receive the heads of the nails 4, as bestshown in Fig. 2, thus reducing the direct strain on the top and bottom2. Said strips may also serve to separate the boxes slightly, so thatthey may be more easily handled. As shown in Fig. 2, the internaldiameter of the box is somewhat greater than the width or length of thesheets of tin-plate T, so that the sheets may be inserted and removedreadily. As such packages are very heavy, a common method of breakingthem open is to dash them to the ground instead of using a tool forwithdrawing the nails. An advantage in the use of this material is thata knife-blade can be inserted and the top or bottom slit around theinner edge of the box quickly and neatly, and the material so cut outcan be again used for box-making or other purposes. If desired, also,the tops of boxes may either be made of one-piece perforated material ormade of two or more pieces with a space between, so that suitableventilation may be provided. Such ventilating-holes are shown in the topin Fig. 1.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

A packing-box for tin-plate the sides and ends whereof are composedentirely of thick wooden pieces, secured together at the corners of thebox where they meet, and the top and bottom whereof are composed of thinpulp-board adapted to be easily cut and of a size to extend over theedges of said side and end pieces, to which they are nailed, thereinforcing-strips 3 being provided outside of 7 said pulp-boards nearthe edges to receive and support the nails, whereby a light, and at thesame time strong and serviceable box for the purpose 'is provided,substantially as set forth.

In witness whereof I have hereunto set my hand and seal at Indianapolis,Indiana, this 2d day of December, A. D. 1899.

JOHN G. MGILWRAITH.
